Simple way to edit or create a pattern. Run the Exchange2 program. Connect the CTX to your PC/Laptop via the cable, and turn it on. Wait until your PC recognizes the new USB (first timers only), and watch the CTX screen until it says it's connected via USB. Now click on the SAMPLES button on the left of the screen. Pick a pattern. Doesn't matter which one. Edit that pattern to how ever you like. Re-name it something that reflects what kind of pattern it's for (ie Trashy Park etc). Now click the SAVE button. You'll now see it listed in the SAMPLES folder. Now to get it to the CTX just click and hold the button down on the pattern, and drag it to the CTX icon at the top and release. To verify it's there just click on the CTX icon and you'll see the new pattern loaded. One last step. Click on the task-bar, and on the USB hub, and click REMOVE USB etc SAFELY. After the PC says it's OK TO DISCONNECT USB wait a few seconds, then you can take the CTX off the cable. Some people have done this too quickly and have lost the new information before it was finished saving. I'll make a step by step video tonight.
